At Cisco we allow up to 1410 bytes upstream and drop fragments. We prefer IPv6
addresses when talking to authorities. We’ve been doing this for years (except
for
a period between Feb 2019 and Aug 2019). Zero customer complaints.
Policy-free addresses are:
2620:0:ccc::2
2620:0:ccd::2
208.67.220.2
208.67.222.2
If you want to experiment.
